Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a fastening method for a fastening enclosure in which the fastening part can be well prevented from rusting, has excellent durability, and has good watertightness and strength. Regarding structure.

[Conventional technology and its problems]

BACKGROUND OF THE INVENTION Conventionally, metal enclosures such as roofs or walls have been constructed. As shown in Fig. 18, this locking structure (other than the place where the hanger is attached) is located at the top a of the bent part on one side of the locking construction board, and on the other side of the adjacent locking construction board. The hanging end edge b of the fastening bent portion is folded downward into a flat shape and crimped. In theory, this kind of construction can be made watertight by fastening, but in reality,
The top part a of the construction board is often undulated in the longitudinal direction, causing deformation and strain.
A plurality of small gaps where capillary action acts are formed between the hanging edges b, which has the disadvantage that rainwater easily enters the inside. In addition, because the fastening edge has a wavy top a in the longitudinal direction, it is often exposed to rainwater, and the edge is particularly prone to corrosion, resulting in poor rust prevention treatment, which reduces durability by half. It was hot.

[Means to solve the problem]

Therefore, in the present invention, vertical parts are formed on both sides of the main plate, a bent part is formed from the upper end of one vertical part, a fastened bent part is formed from the upper end of the other vertical part, and the end of the fastened bent part is formed. The curved part of the construction board having an arcuate edge formed thereon is fitted with the bent part of the adjacent construction board, and the end face of the arcuate edge is connected to the adjacent construction board. By adopting a locking structure in which the locking outer body is in close contact with the vertical part of the plate, the locking part can be well prevented from rusting, which in turn enables long-term durability, and has excellent watertightness and strength. The above-mentioned disadvantages can be solved simply by using this method.

〔Effect of the invention〕

In the present invention, vertical portions 2 are provided on both sides of the main plate 1,
2, and a bent part 3 is formed from the upper end of one vertical part 2.
A bent part 4 is formed from the upper end of the other vertical part 2, and an arc-shaped edge 5 is formed at the end of the bent part 4.
The bent part 4 of the adjacent construction board A is fitted onto the bent part 3 of the board A that has been formed, and the end face of the arc-shaped edge 5 is attached to the bent part 3 of the adjacent construction board A. By closely adhering to the vertical part 2 of the construction board A, firstly, the fastening part can be well prevented from rusting, which in turn makes it possible to guarantee long-term quality, making it extremely durable. 2. It has good watertightness (rain protection),
Thirdly, the strength can be improved, and fourthly, dimensional errors can be adjusted.

To explain these effects in detail, the corrosion of the clamped parts generally begins at the clamped ends, and the corrosion due to battery action (commonly known as ``electrical corrosion'') quickly spreads to the entire clamped part. However, if the end surface of the arc-shaped edge 5 is in close contact with the vertical part 2 of the fastening construction board A, the end of the arc-shaped edge 5 will simply be fitted or folded back and tightened. As a result, the edges of the construction board A can be made to have a structure that is extremely resistant to corrosion. The entire part has excellent corrosion resistance, and its durability can be maintained over a long period of time. In recent years, there has been a particular demand for fastened enclosures such as roofs that have excellent corrosion resistance and are durable. The present invention satisfies the requirement for durability guaranteed for 20 to 20 years. Moreover, even if the end surface of the arc-shaped edge 5 is in close contact with the vertical part 2 of the fastening construction board A, a hollow part is always formed between the bent part 3 and the fastening bent part 4, This makes it possible to prevent the capillary phenomenon of rainwater and reliably block rainwater from entering from the closing part, thereby providing a closing structure with excellent rain closure (watertightness). Therefore, the present invention can overcome the drawback of poor rain sealing (watertightness) even when folded and crimped into a flat shape etc. and tightened as in the conventional method. In addition, the presence of the arc-shaped edge 5 makes the finish of the end of the fastened construction board A neat and orderly without waving in the longitudinal direction, increases the section modulus, and further strengthens the fastened part. can. By the way, coil steel sheets, which are the base material for forming conventional construction boards, have a tolerance dimension on the plus side, and when this is roll-formed, the The fastening edge is often formed with a wide width, which causes variations in product dimensions, which reduces the product value by half, and has drawbacks such as being unable to be constructed or extremely difficult to construct even if it is attempted. However, according to the present invention, it is possible to easily widen only the arcuate edge 5 side, and in this way, it is possible to make the construction board A with precision in appearance, and also to create a roof or roof that can be constructed neatly and reliably. Can provide a tight enclosure such as a wall. In addition, the edges of standard coiled steel plates are generally better rust-proofed than other parts, and by not using a slitter, good rust-proofing can be achieved.
